Sorry - your memory is playing tricks on you. Mackie and Haynes were at ITV when The Palace, Rock Rivals, Whistleblowers, Harley Street and many other duds were commissioned.
They've revived the channel's drama fortunes in part since then but at the expense of any originality - their hits are either carbon copies of other shows or linked to existing franchises. It's been enough to spin a PR line about 'a drama rennaissance' - but that's not strictly true ... and for every hit there have been many more flops. They certainly haven't got the channel back to where it used to be, churning out one drama smash after another and flattening the opposition. And yes, I know viewing habits have changed and there are more channels than there used to be - but a major hit is still a major hit, and ITV has nothing like as many in drama as it used to have.
True. Itv has had three returning hits: Downton abbey, whitechapel and Scott and Bailey as well as middling crime shows like Law and order and Inspector banks. Thats not many proper returning hit shows in the space of five years. Last year none of their new dramas rated well. BBC's Ben Stephenson in less time has found: Sherlock, Call the Midwife, Luther, Last Tango in Halifax, Death in Paradise, The Paradise, Silk which is not only more shows but a wider range of genres.
